Abstract
Para transmitir una senal de multiples portadores, un transmisor provee símbolos cero para subbandas de guarda, lleva a cabo la modulacion de OFDM, y filtra las muestras en el dominio del tiempo resultantes con un filtro de configuracion de pulsos. Para transmitir una senal de un solo portador, el transmisor particiona la senal de un solo portador en segmentos. Cada segmento contiene hasta que K muestras y es atenuado, en caso de necesidad, a la longitud de un símbolo de OFDM. Cada segmento atenuado se transforma del dominio del tiempo al dominio de la frecuencias para generar un correspondiente segmento en el dominio de las frecuencias con K símbolos. Para cada segmento en el dominio de las frecuencias, los símbolos correspondientes a las subbandas de guarda son puestos en cero. Cada segmento en el dominio de las frecuencias es seguidamente transformado desde el dominio de las frecuencias al dominio del tiempo para generar un correspondiente segmento en el dominio del tiempo. Puede haber o no un prefijo cíclico adjuntado a cada segmento en el dominio del tiempo. Cada segmento en el dominio del tiempo es filtrado con el mismo filtro de configuracion de pulsos para generar una forma de onda de salida para la senal de un solo portador.To transmit a multiple carrier signal, a transmitter provides zero symbols for guard subbands, performs OFDM modulation, and filters the resulting time domain samples with a pulse configuration filter. To transmit a single carrier signal, the transmitter divides the single carrier signal into segments. Each segment contains until K samples and is attenuated, if necessary, to the length of an OFDM symbol. Each attenuated segment is transformed from the time domain to the frequency domain to generate a corresponding segment in the frequency domain with K symbols. For each segment in the frequency domain, the symbols corresponding to the guard subbands are set to zero. Each segment in the frequency domain is then transformed from the frequency domain to the time domain to generate a corresponding segment in the time domain. There may or may not be a cyclic prefix attached to each segment in the time domain. Each segment in the time domain is filtered with the same pulse configuration filter to generate an output waveform for the single carrier signal.
